I'm liking the 10mm f2.8!

I almost didn't buy the 10 f2.8, but could not resist a $99 "By It Now" price on eBay and I'm so glad I did! Compared 10-30 kit lens, the 10 f2.8 focuses faster, has better color and much better micro-contrast and is sharper at the edges, even at f2.8. The 10mm lens improves the image quality of the V1 substantially, IMO.
